Mei Hero Mastery
Recruit Score: 7303.3
This is rank 44 right now about 2 hours after release.
Got this after a couple of tries. Feels like there's no way to get all coins and still get the 3x multiplier here. Still not sure when or if I should use the ice block here.
Edit: Improved it to 7394.4 now. Got one more coin and used the freeze spray on a couple of robots to get a better score. This has to be the easiest hero mastery yet. I think they could have made it a bit better though. If you needed to use the wall or iceblock to block damage from robots for example.
